Since commit ("selftests: error out if kernel header files are not yet built") got merged, the kselftest build correctly because the KBUILD_OUTPUT isn't set when building out-of-tree and specifying 'O=' This is the error message that pops up.

Fixing the issue by assigning KBUILD_OUTPUT the same way how its done in kselftest's Makefile. By adding 'KBUILD_OUTPUT := $(O)' 'if $(origin O)' is set to 'command line'. This will set the the BUILD dir to KBUILD_OUTPUT/kselftest when doing out-of-tree builds which makes them in its own separete output directory.

This should get squashed into the original patch unless it's already in mm-stable (which it isn't) and we have a stable commit id.
